TECHNICAL FIELD TO WHICH THE INVENTION REFERS

The present invention relates to an electrical equipment support comprising a frame defining a reception opening of an electrical equipment mechanism, bordered by means for receiving the electrical equipment mechanism, and at least two uprights extending from this frame, perpendicular to it, facing one another, and which each comprise a mounting means of the support in a wall.

BACKGROUND

Document FR2937802 discloses in particular such an equipment support in which each upright is provided with gripping claws of the support on a wall.

Such a support has the disadvantage of being relatively long to install, because it is necessary to actuate the claws by screwing a screw so as to make them take an inclined position towards the outside of the support frame. In this inclined position, the claws are supported on a rear face of the wall, which is then sandwiched between the frame and the claws of the support.

These operations can be perceived as long and tedious for the operator.

Also known from GB2183107 is an apparatus support comprising two uprights each carrying, on the one hand, means for receiving by screwing an electrical equipment mechanism, and, on the other hand, means for mounting the support in a wall. This support also has the disadvantage of being relatively long to install. This installation also requires the use of tools.

In Figures 1 to 12 and 20 to 22, there is shown a support 100; 200; 300 of an electrical apparatus (not shown) for direct attachment, i.e. without a flush-mounting box, in a hollow mounting wall 10A (FIGS. 10 to 12). This mounting wall 10A comprises a front panel 10 facing the user and a rear panel (not shown) separated from the front panel by a free space.

Only an inner face 13, facing inwardly of the mounting wall 10A, of the front panel 10 is shown in FIGS. 10 to 12.

The mounting wall 10A may in particular be an electrical chute, mounted inside a partition wall or behind a plasterboard. It may also be any masonry element, brick type or cell wall element type provided with channels for passage of electrical ducts.

As explained in more detail later, when mounting the support 100; 200; 300 in the mounting wall 10A, an opening January 1 is formed in the front panel 10 of the mounting wall 10A (Figures 10 to 12) and a portion of the support is passed through this opening January 1.

The support 100; 200; 300 makes it possible to mount one or more switchgear mechanisms in the mounting wall 10A, for example a switch, socket, telephone socket or TV / SAT socket, RJ plug or socket television.

In the examples shown in the figures, the support 100; 200; 300 is intended to accommodate at least one equipment mechanism 360. This equipment mechanism 360 is shown in Figures 21 and 22.

Thanks to the support according to the invention, the bottom of the base of this equipment mechanism is thus housed directly inside the mounting wall. This allows a direct electrical connection of the switchgear mechanism to power cables flowing in the mounting wall.

In the remainder of the description, the terms "before" and "back" respectively denote, when the support 100; 200; 300 is attached to the mounting wall 10A, the location facing the installer and the inward facing location of the mounting wall 10.

The terms "inside" and "outside" mean respectively the place facing the center of the support 100; 200; 300 and the place turned to the opposite.

The support 100; 200; 300 here comprises a frame 1 10; 210; 310 delimiting an opening 1 13A; 213A; 313A for accommodating said mechanism of electrical equipment, and at least two amounts 120; 220, 230; 320 extending from this frame 1 10; 210; 310, perpendicularly thereto, facing each other, and which each comprise a means for mounting the support 100; 200; 300 in the mounting wall 10A (Figures 1 and 20).

The support 100; 200; 300 is made of an electrically insulating material, for example plastic. Frame 1 10; 210; 310 and the amounts 120; 220, 230; 320 are then preferably obtained in one piece, by molding a plastic material.

Frame 1 10; 210; 310 has four planar branches, and is defined between an outer peripheral edge 1 15; 215; 315 and an inner peripheral edge 1 13; 213; 313 which delimits said opening 1 13A; 213A; 313A reception.

It has a front face 1 1 1; 21 1; 31 1 and a rear face 1 12; 212; 312 opposite.

Frame 1 10; 210; 310 here has a generally square shape, and its opening 1 13A; 213A; Host 313A is also square in shape (Figure 4).

Alternatively, the frame and its opening may have any other suitable form. The frame may be in particular rectangular or circular and the reception opening may be rectangular or square, for example.

Aperture 13A; 213A; 313A of the frame 1 10; 210; 310 is bordered by receiving means of the electrical equipment mechanism 360 (not shown in Figures 1 to 20).

In the first and second embodiments, these receiving means comprise a flange adapted to cooperate with a base of the fitting mechanism, which is then attached to the support. This rim is here in the form of a sidewalk 1 16; 216 bordering internally all of this opening and adapted to receive by snapping an edge of the base of the fitting mechanism (Figures 1, 2 and 20).

Alternatively, it may be a sidewalk bordering only two opposite sides of the home opening.

The flange may also be formed by a plurality of tabs extending within the receiving opening.

This rim may comprise means for receiving the equipment mechanism, for example by snapping or screwing. In the third embodiment, shown in FIGS. 21 and 22, said receiving means comprise an insulating base 350 forming with the frame 310 of the support 300. This insulating base 350 houses the fitting mechanism 360.

Thus, whatever the embodiment of the support envisaged, the receiving means of the equipment mechanism are carried by a part of the support - sidewalk 1 16; 216 or insulating base 350 - separate from the uprights. Amounts 120; 220, 230; 320 are different parts from those comprising the receiving means and are not involved in fixing the fitting mechanism in the support 100; 200; 300. Thus, the amounts 120; 220, 230; 320 are implemented independently of the receiving means of the fitting mechanism.

The axis of the frame 1 10; 210; 310 is defined as the axis which passes in the center of this opening 1 13A; 213A; 313A of reception and which is orthogonal to the frame 1 10; 210; 310. It is hereinafter referred to as "main axis A1; A2; A3 "of the support 100; 200; 300 (FIGS. 1, 2, 3, 4 and 20).

To finalize the aesthetic appearance of the electrical equipment, the front face 1 1 1; 21 1; 31 1 and the portion of the frame 1 10; 210; 310 of the support 100; 200; 300 of electrical equipment are intended to be covered by a finishing plate (not shown in the figures) in the form of a frame, so that the inner edge of this finishing plate borders the equipment mechanism attached to the support 100 ; 200; 300 and that the outer edge of this finishing plate is based on a front face 12 of the front panel 10 of the mounting wall 10A, facing outwardly of this wall.

Each of the four branches of the frame 1 10; 210; 310 comprises for this purpose fixing means for fixing the finishing plate (not shown) on the support 100; 200; 300. These fixing means may be for example latching means.

Amounts 120; 220, 230; 320 of the support 100; 200; 300 extend from the rear face 1 12; 212; 312 of the frame 1 10; 210; 310.

There are two in the first and third embodiments shown in Figures 1 to 12 and 21, 22 and four in the second embodiment shown in Figure 20.

These amounts 120; 220, 230; 320 come here in the form of tabs slightly bent around the main axis A1; A2; A3.

More specifically, regardless of the number of amounts, they are preferably arranged so that their sections in a plane perpendicular to the main axis A1; A2; A3 of the support 100; 200; 300 follow the outline of a circle. This form makes them particularly suitable for mounting the support 100; 200; 300 in the opening 1 1 of the mounting wall 10A, when the opening 1 1 has a circular shape, obtained for example by cutting with a hole saw. This is clearly visible in FIG.

Of course, other shapes may be envisaged for the section of the uprights, in particular a cross section adapted for mounting in a square or rectangular opening.

Remarkably, said mounting means carried by the uprights 120; 220, 230; 320 are latching mounting means and the support 100; 200; 300 further comprises locking means adapted to prohibit the disengagement of these mounting means.

Specifically, each amount 120; 220, 230; 320 comprises a latching lug 121; 221, 231; 321 provided on its outer face 121A; 221A, 231A; 321A of a ratchet tooth 122; 222, 232; 322 having a bearing surface 122A; 222A, 232A; 322A parallel to said rear face 1 12; 212; 312 of frame 100; 200; 300.

Each latching lug 121; 221, 231; 321 is cut in the amount 120; 220, 230; Corresponding 320 of the support 100; 200; 300. It presents here a rectangular shape with rounded corners and remains connected to the amount 120; 220, 230; 320 by a root near the free end of this amount. The root of each latching lug corresponds to one of the sides of the rectangle formed by said latching lug.

Thus, the latching lug 121; 221, 231; 321 is adapted to flex around this root, especially towards the inside of the support.

The ratchet tooth 122; 222, 232; 322 here further comprises an inclined pan 124; 224, 234; 324 connecting the free edge of the bearing surface 122A; 222A, 232A; 322A of this detent tooth to a portion of the latching lug 121; 221, 231; 321 corresponding to the side of the free end of the amount 120; 220, 230; 320 corresponding to the support 100 with respect to this bearing surface 122A; 222A, 232A; 322A. Here, the inclined pan 124; 224, 234; 324 extends between the bearing surface 122A; 222A, 232A; 322A of the ratchet tooth and the root of the corresponding ratchet.

Here, the inclined pan 124; 224, 234; 324 is formed by the slice of three partitions extending perpendicularly to the bearing surface 122A; 222A, 232A; 322A of the detent tooth and perpendicular to a mean plane of the corresponding latching lug.

The locking means comprise at least one movable locking element between a release position (Figure 2) in which it allows the deflection of each latching lug 121; 221, 231; 321 and a locking position (Figure 1) in which it prohibits this deflection.

For this purpose, the locking element comprises, in the locking position, at least one portion positioned facing the inner face of each latching lug 121; 221, 231; 321 cooperating with the mounting wall 10A, so that this part forms an anti-recoil stop of the corresponding latching lug.

To act on said latching lug, the locking element is inserted between the latching lug concerned and the receiving means of the fitting mechanism, that is to say between the latching lug and the latching lug. edge of the support opening (first and second embodiments) or between the latching lug and the base for accommodating the fitting mechanism (third embodiment).

To allow the positioning of this part of the locking element facing the inner face of the latching lug 121; 221, 231; 321 from the front of the frame 1 10; 210; 310 of the support 100; 200; 300, frame 1 10; 210; 310 of the support 100; 200; 300 has an access port 1 14; 214; 314, adapted to be traversed by a portion of the locking member (Figures 2, 20 and 21).

The locking element is preferably simply fitted into the support 100; 200.

More specifically, here, said locking means comprise two locking elements 130 in the form of removable pins.

The two pins 130 are identical. They are more particularly represented in FIGS. 13 to 18. Each pin 130 is adapted to be mounted on the support 100; 200, in a position in which it prevents the deflection of one of the latching lugs 121; 221, 231; 321. The two pins 130 thus block the bending of two opposite latching lugs.

More specifically, each pin 130 comprises, as represented in FIGS. 13 to 18, a head 131 and a body 132. The body 132 here comprises two studs arranged one beside the other, which extend perpendicular to the head 131. Each of these pads is hollow, which allows material savings and lightening of the pin 130 (Figure 15).

The head 131 extends slightly overflow around the body 132 (see Figures 15 and 18).

The slice 131 A of the head 131 of the pin 130 (FIGS. 13 to 18) has a width which progressively fades from the body 132 of the pin 130 to the front face of this head 131, intended to extend into the extension of the front face 1 1 1; 21 1; 31 1 of the frame 1 10; 210; 310 when the pin 130 passes through the access port 1 14; 214; 314 of the support 100; 200; 300.

The portion of the access port 1 14; 214; 314 has a complementary profile (Figures 6 to 9), so that the head 131 is held in the access port 1 14; 214; 314 and the pin 130 does not slide entirely through the access port 114; 214; 314.

When the pin 130 is disposed in the corresponding access port, and maintained by the cooperation of its head 131 and this access port, the body 132 of the pin extends at least partially opposite the leg of the snap-fastening 121; 221, 231; 321 nearest. It thus forms a stop for this latching lug preventing its bending towards the inside of the support.

Advantageously, in order to reinforce the holding of the pin 130 on the support, the locking means of the support 100; 200; 300 here also comprise a housing 140; 240; 340 (Figures 3 and 22) formed projecting from the inner face 121 B; 221 B, 231 B; 321 B of each latching lug 121; 221, 231 and adapted to receive said pin 130. This housing 140; 240; 340 is disposed between the receiving means of the electrical equipment mechanism and the latching lug.

It forms guide means for the corresponding pin 130, and prevents any lateral movement of the pin, that is to say any movement other than a movement along the longitudinal axis of the housing, parallel to the latching lug.

This housing 140 is more particularly represented in the case of the first embodiment in FIG. 19.

It has a shape adapted to receive a part of the body 132 of the pawn

130.

Accordingly, the housing 140 here has two compartments 141, 142 (Figure 19) each adapted to receive, at least partially, one of the pads of the body 132 of the pin 130.

These two compartments 141, 142 are delimited on a first of their sides by the inner face 121 B of the latching lug 121.

Partitions 143 protrude from this internal face 121 B and are closed, on a side opposite to the inner face 121 B of the latching lug 121, by a longitudinal wall 144.

The two compartments 141, 142 extend generally in a direction parallel to the main axis A1 of the support 100. Their two longitudinal ends are open.

Alternatively, the longitudinal end of the housing 140 furthest from the frame 1 10 could be closed.

The housing 140 extends from the upper end of the latching lug 121, the closest to the frame 1 10 (see Figure 5).

Each dwelling 140; 240; 340 is particularly adapted to keep in place the studs of the corresponding pin 130, facing the latching lugs 121; 221, 231; 321. Said access orifices 1 14; 214; 314 of box 1 10; 210; 310 are arranged facing the corresponding longitudinal end of the housing 140; 240; 340. Thus, each dwelling 140; 240; 340 is accessible on the front face of frame 1 10; 210; 310 through this access port 1 14; 214; 314 of box 1 10; 210; 310.

The pins 130 of the second and third embodiments of the support 200; 300 are not shown in Figures 20 to 22. The housings 240; 340 of the second and third embodiments are visible in Figures 20 and 22. The two pins and the four housing 240 of the support 200 according to the second embodiment are identical to those described with reference to the figures showing the first embodiment. Similarly, the two pawns and the two housings 340 of the support 300 according to the third embodiment are identical to those described with reference to the figures showing the first embodiment.

Alternatively, in the third embodiment, it is conceivable that the housings are arranged projecting from two opposite side walls of the insulating base of the fitting mechanism, facing the access holes of the corresponding frame.

As mentioned above, the second embodiment of the support 200 differs from the first and third embodiments in that there are provided two uprights 220, 230 two opposing pairs, each provided with a latching lug 221, 231.

The bearing surfaces 222A of the ratchet teeth 222 of a first pair of opposite posts 220 are spaced apart from the rear face 212 of the frame 210 by a first distance H1, while the bearing surfaces 232A of the teeth of FIG. snap 232 of the second pair of opposite uprights 230 are spaced from the rear face 212 of the frame 210 by a second distance H2, different from the first distance H1.

In a particularly advantageous manner, this arrangement allows mounting of the support 200 on mounting walls having two different thicknesses.

In practice, for mounting the support 100; 200; 300 in the mounting wall 10A (Figures 10 to 12), the user first of all the opening 1 1 in the front panel 10 of the mounting wall.

This can be done in different ways. In the examples shown here, this opening 1 1 of the mounting wall 10A is circular. It is pierced for example by means of a hole saw.

Of course, other forms can be envisaged for opening the mounting wall and other tools for piercing it.

The dimensions of this opening 1 1 of the mounting wall 10A are predetermined depending on the support used.

As can be seen in FIG. 11, these dimensions must allow the bearing surfaces 122A; 222A, 232A; 322A ratchet teeth 122; 222, 232; 31 1 of at least two opposite snap lugs to bear against the inner face 13 of the front panel 10 of the wall mounting 10A.

Then, the installer pushes the amounts 120; 220, 230; 320 of the support 100; 200; 300 through the opening 1 1 of the mounting wall 10A.

In doing so, the free end of the uprights 120; 220, 230; 320 slides in the opening 1 1, then, when the inclined pan 124; 224, 234; 324 ratchet teeth 122; 222, 232; 322 comes against the edge of the opening January 1, the latching lugs 121; 221; 231; 321 flex inwardly of the support 100; 200 and the sliding continues along this inclined pan.

At the end of the stroke of inclined section 124; 224, 234; 324, the resilience of the latching lug 121; 221, 231; 321 returns it to its original position.

Thus, the bearing surface 122A; 222A, 232A; 322A ratchet teeth 122; 222, 232; 322 is positioned opposite the inner face 13 of the front panel 10 of the mounting wall 10A.

The distance H1, H2 (FIGS. 1 and 20) between the bearing surface 122A; 222A, 232A; 322A of the ratchet teeth of at least one pair of opposite uprights and the rear face 1 13; 213; 313 of box 1 10; 210; 310 is chosen to correspond, with a clearance, to the thickness E (Figure 12) of the front panel 10 of the mounting wall 10A on which the support 100; 200; 300 is mounted.

Accordingly, when the bearing surface 122A; 222A, 232A; 322A is positioned against the inner face 13 of the front panel 10 of the mounting wall 10A, the rear face 1 12; 212; 312 of the frame 1 10; 210; 310 is positioned simultaneously against the front face 12 of the front panel 10.

The support 100; 200; 300 is thus snapped into the mounting wall

10A.

As explained above, in the case of the first and third embodiments, the support 100; 300 can be latched only in mounting walls whose front panel 10 has a given thickness, corresponding to the distance H1 between the bearing surface 122A; 322A and the rear face 1 13; 313 of box 1 10; 310, while in the second embodiment, the support 200 can be snapped onto mounting walls whose front panel 10 has one or the other of two different thicknesses, corresponding to the different distances H1, H2 between the surfaces. 222A, 232A of the ratchet teeth of two pairs of opposite uprights and the rear face 1 12, 212 of the frame 1 10, 210. In the case of fixing the support 200 according to the second embodiment on a front panel 10 whose thickness is equal to the distance H2 largest between the bearing surfaces 232A of the ratchet teeth and the rear face 212 of the frame 210, the other locking lugs 220 carrying the ratchet teeth 222 whose bearing surface is spaced a distance H1 from the lower rear face of the frame remain bent towards the inside of the support 200, in a free volume that does not interfere with the introduction of the fitting mechanism.

In order to ensure the holding of the support on the partition and prevent unintentional tearing of the support, the pins 130, here constituting the locking element, are inserted into the housing 140; 240; 340 corresponding through the access ports 1 14; 214; 314 of box 1 10; 210; 310 disposed opposite housing 140; 240; 340.

The body 132 of each pin 130 then comes to be partially housed inside one of these housings 140; 240; 340, while the head 131 is housed in the thickness of the frame 1 10; 210; 310.

The body portion 132 of each pin 130 which is housed in the housing 140; 240; 340 then extends facing the inner face 121 B; 221 B, 231 B; 321 B of the corresponding latching lug. Consequently, this part of the body 132 of the pin 130 forms an anti-recoil stop for this latching lug, which can no longer bend towards the inside of the support 100; 200; 300.

This deflection being blocked, the support 100; 200; 300 can not be disengaged from the mounting wall. The mounting of the support in the mounting wall is thus secure.

In addition, this assembly is very fast and easy to implement. It can be done manually, without using tools.

Alternatively, said locking means may comprise a single locking element comprising two pins secured to each other.

In another variant, the body of each locking pin may have only one stud. As a result, the housing that hosts it does not have a central partition.

The locking means may in particular be in the form of a jumper whose two free ends form said pins.

According to a particularly advantageous variant, said pins may be integral with the finishing plate intended to be attached to the front face of the support frame.

In this case, the pins protrude from a rear face of the finishing plate.

In the variants described above, the fact of joining the two locking pins in a part having a rigid structure makes that the presence of a housing in the inner face of each latching lug, or projecting from the insulating base in the third embodiment is not essential. Indeed, in this case, the pin forms a stable and indeformable stop. It is not necessary to block it with the housing to prevent the recoil from falling back into the support.

It is also possible that each pin comprises at its head snap means on the frame of the support. The support then comprises complementary latching means. In this case, the pin is held by these latching means and the presence of a housing for receiving the pin is optional.

An example embodiment is described here in which the detent tabs are cut in the corresponding amount, with a root located near the free end of this amount. Alternatively, it is conceivable that one or more latching lugs is cut in the corresponding amount with a root near the base of the amount, that is to say oriented towards the frame of the support.

The free end of the latching lug is then oriented towards the free end of the upright.

The ratchet tooth then remains similar to that described above. It then comprises an inclined section which extends between the bearing surface of the detent tooth and the free end of the latching lug.
